    Best Price on Q-Switched Material - Dual Wavelength Waveplates – Dien

    Dual wavelength waveplate is widely used on Third Harmonic Generation (THG) system. When you need a NLO crystal for type II SHG (o+e→e), and a NLO crystal for type II THG (o+e→e), the  out put polarization from SHG can not be used for THG. So you must turn the polarization to get two perpendicular polarization for type II THG. Dual wavelength waveplate works like a polarizing rotator, it can rotate the polarization of one beam and remain another beam’s polarization. Recommend Standard W...

    New Delivery for Yag Lens - Achromatic Depolarizers – Dien

    These achromatic depolarizers consist of two crystal quartz wedges, one of which is twice as thick as the other, that are separated by a thin metal ring. The assembly is held together by epoxy that has been applied only to the outside edge (i.e., the clear aperture is free from epoxy), which results in an optic with a high damage threshold. These depolarizers are available uncoated for use in the 190 – 2500 nm range or with one of three antireflection coatings deposited on all four surf...
